I just cut loose a few communities and some journals that haven't been updated in ages. If you've posted in the last 12 months, I'm NOT talking about you. And, if you haven't posted or commented recently but I know you in real life, I also will have kept you on. The people I cut are very likely never coming back to LJ. One hadn't posted since summer of 2006!
But, just in case I cut someone who has been reading and just not posting, feel free to drop me a line and I'll add you again- it was nothing personal, just a bit of spring cleaning.
